AMS Safety Adapter – Secure Your Prints in Style

Ever had a filament spool fall off your Bambu Lab AMS Lite - sometimes mid-print or even in the middle of the night? You’re not alone. That’s exactly why I designed this elegant, economical, and practical safety adapter.

Simply push it onto the AMS hub and, with a quick twist of the wrist, the spool is secured in place - adding that extra layer of protection and peace of mind for those long, unattended prints.

Inspired by the tactile feel of high-end camera aperture rings, this version doesn’t just look good - it’s also efficiently optimized for fast, material-saving printing without sacrificing function or durability.

✅ Prevents spool dismounts

✅ Quick and easy to print

✅ No supports needed

✅ Lightweight yet strong

✅ Clean, ergonomic design (check out the photos)

Note: This adapter was primarily designed for SUNLU spools, which are AMS Lite compatible but often sit a bit loose and may fall off due to vibrations - especially if your printer and AMS share a table. It may not fit deeper cardboard spools like those from ELEGOO. I recommend printing one to test fitment.

I always welcome feedback and observations from the community - feel free to let me know which spool brands this works great with or where compatibility is limited. Your input helps improve the design for everyone!
